FLUE SYSTEM FOR RETORT COKE OVENS .Application filed September 19, 1921; Serial No. 501,577.

My invention relates generally to coke ovens having horizontally disposed heating yflues and more particularly to ovens of this class whichA are. provided with two sets of flues on each side of the oven separated by a dividing wall and the object of my improvenected with the oppositely located set on the other side of the oven, so that the .two sets form independent heating units, and each of theseheating units is connected withits own set of regenerators. Thus, while obtaining an etlicient heat supply for thewhole Oven, I provide for the independent regulation of the temperature of the two ends thereof,as is frequently desirable.

The invention will be best understood by reference to the accompanying drawings illlustrating an embodiment thereof, Fig. 1 of which shows an end view of a battery of coke ovens, partly broken away' and depicted in section to show the heating flues ;v Fig.

2 shows a vertical cross section through the -oven and heating flues on the line 2 2 of Fig. l, and Fig. 3 shows a horizontal sectional view of a single oven taken onv the line 3 3 of Fig. l. p

Referring to the drawings, A, indicates the' coking chamber, on each side ofvwhich are two sets of independently operative heating flues, B, B' which are located inv dividing walls between the coking chambers and are separated by a dividing wall l/V.

Below each oven'and'its heating flues are two sets of regenerators, C, C', D, D', ofthe usual checker work brick construction, and

- `below the regenerators are iues E, E', F, F',

disposed longitudinally of the battery of ovens for the conduction of air toand the reception yof the hot gases of combustion from the regenerators. The lines E, F', are connected together at the reversing valve f or conduits h, 7L, withthe regenerators C',

(not shown in the drawings) as are also vthe flues E', Fn

The fluesE, F', are connected by passages (1,12, with regenerators C, D', and the lues E', F, are connected .by passages c, d, with regenerators C', D. The regenerators C, D',

Vare respectively connectedpby ports e, f, with sole flues, G, G', located under the chamber or inthe bottom wall of thevcoling chamber A, each of which extends the lengthvof one of the sets of heating flues, B, B', and which are separated by the dividing wall W.

The sole flues G, G', are respectively connected by ports g, g', and .conduits 12 with the lowermostflues, l,Y of the `,two sets of heating fluesB, B', on one side of the oven, land lthe corresponding lowermost flue-s of the two sets of heating flues on-k the other side of the oven are `connected by.- passag The-uppermost flues 6, of the-two sets'of are connected bycross-over fines or passages .H, H', which pass through thebrickwork v ining the chamber and communicate with the above the oven, or through the top wall de- Vheating iues, B, B', on one sideof the oven nected-at the reversing valve and act asa single f1ue,the air from the flues'E, F', enters the regenerators C, D', through the ,passages r 0;, 7;, and thence by ports c, f, into the sole flues G, G'. From the -soleflues G,G', the fair enters ,the flower heating iues 1,'1, by ports g, g', and risesV through the heating Afines' tothe uppermost flues 6, 6, whence it crosses by transverse passages H, H,'to .the

A:other side of the oven cnteringthe corre-1.k

spending uppermost heating flues on that side and passes down throughthe heating iiues.y In vpassing through the flues the air supports the cobustion of fuel gas rissuing from burnersy 10which are associated with the heating flues and which are connected to C, D, and thence by passages c, d, to lues Ff, F, and through these to the stack.

On the reversal the air, entering from flues E', F, asse-s into regenerators, C, l), and thence by passages h, into the lowermost heating flues l', and upward through the heating dues to the upper iue 6', whence it crosses over by passages H, H', to the upper heating' flue 6, on the other side of the oven, and passes downward through the heating flues. The hot gases of combustion pass from the lower heating flues l, l, by ports, g, g',

into sole flues G, Gr, and from thesole flues by ports e, j', into regenerators C, D, and thence by passages a, b, to flues E, F, and to the stack.

From the foregoing it will be evident that the flow of gases through each of the two sets of heating flues B, B, is independent of that through the otherl and the tempera,- tures of the two ends of the oven can be separately controlled and regulated. Moreover, since a separate regenerator is provided for each half of the oven the dividing ofV the air current in the regenerator, as at present is eliminated.

Having thus described my invention, what 'I claim as new and desire to secureiby Letters Patent is Y 1 l. A coke oven comprising in combination a horizontally elongated coking chamber, two

independent heating systems for said colring chamber, one of said heating systems extending a portion of the length of said chamber, and the second of said heating systems eX- -tending for another portion of said colring chamber, each of said heating systemsv comprising the hereinafter recited iiues, passages, conduits, and regenerators, to wit, a combustion flue on each of opposite sides of said cokingy chamber, each of the combustion lines comprising zig-zag series-connected superimposed horizontal passages, a cross-over flue extending over the top of said colring chamber and communicating withV each of the uppermost of said horizontal passages on opposite sides of said colring chamber, conduits respectively individual to and communicating with each of the lower-most of said horizontal passages on opposite sides of said colriiig chamber, and four reversible regenerators arranged in a row beneath the coking chamber longitudinally thereof and communicating with the flues.y

2. In a coke oven, a horizontally elongated coking chamber, a heating system for said coking chamber comprising a` combustion flue on opposite sides of said coking chamber, each of the combustion flues comprising zigzag series-connected superimposed horizonhorizontal passages on opposite sides of said cokmg chamber, apair of reversible regenerators positioned beneath said coking cham'- ber parallel thereto, the individual members of said pair being positioned in alignment longitudinally of said colring chamber, a conduit individual to and communicating with the lowermost of said horizontal passages on one side of said colring chamber and with one of said pair of regenerators and a second conduit individual to and communicating with the lowermost of said horizontal passages on the other side of said coling chamber `and with the other of said pair of regenerators.

3. A coke oven battery comprising horizontally elongated colring chambers and heating walls therefor arranged side-by-side in alternate relation, each of said heating walls being composed of four sets of zig-zag seriesconnected superimposed horizontal passages arranged in groups of two disposed adjacent the side of each colring chamber, cross-over flues extending over the tops of said coking chambers and communicating with `each of the uppermost of said two groups of horizontal passages on opposite sides of each coking chamber, reversible regenerators Y disposed in groups, each of said groups having four regenerators in a row,each of said coking chambers having one of the rows of regenerators therebeneath and parallel therewith, each of said rows of regenerators being individual to and communicating with the lowermost horizontal passages of, the .two sets of horizontal passages on opposite sides of the colring chamber thereabove.

Y 4. A coke oven battery comprising horizontally elongated colring chambers and heating walls therefor arranged side-by-side in alternate relatiomeach of said heating walls being composed of four sets of zigzag series-connected superimposed horizontal passages ar- Ycoking chamber, cross-over flues extending over the tops of said colring chambers and communicating with each of the uppermost of said two groups of horizontal passages on opposite sides of each coking chamber, reversible regenerators disposed in groups of four regenerators, each lof said colrin chambers having one of said groups there eneath and the regenerators in the group being arranged in alignment longitudinal of the coking chamber theieabove, each of said groups of four regenerators being individual to and communicating with the loweimost horizonktal passages ofthe two sets of horizontal passages on opposite sides of the coking chamber thereabove.

ln testimony whereof I affix my signature, this 15th day of September, 1921.
